    Mike,
       Go here - [1]http://www.cru.uea.ac.uk/cru/data/temperature/
    and scroll down to where you can download the HadCRUT3
    data for the Globe. You can also get NH and SH separately
    and the HadCRUT3v version is also there.
       In the global column the value for 2008 is based on the first
    7 months of the year.
       There are several ways to answer the question
    1. Extract the SOI signal from the global T record.
    2. The easiest though is just to put a regression line through
    the values from 1998 to 2007. This gives a +ve trend, but not
    sig as you'd expect. Adding 2008 may make the trend -ve,
    but it still wouldn't be significant.
     La Nina is the reason, as you know for the cooling. As soon as
    we get an El Nino, then ...
     It is not me doing the WW2 adjustments. It does seem to be taking MOHC
    some time to do this. I reckon they are trying to add in more of the newly
    digitized British SST data for the period.
    Cheers

     In order for me to answer the second question below, shown in red, please send me your

     In a related matter, when do you anticipate completing the correction for the post-1945
     temperature error that result from the British navy's resumption of bucket SST
     measurements then?

     Jim:

     I am passing your email along to my friend Michael Schlesinger at U. Illinois-Urbana,
     who is one of the world's most well-regarded climate scientists and an authors of dozens
     of referred articles on climate change.

     Michael, when you have a minute, would you mind addressing Jim's two central claims:
     that (a) 'There is to date, nothing in today's climate nor in the recent past which
     falls outside of the variability of normal climate change and that (b) 'since 1998,
     average global temperatures have been falling in spite of rising CO2 levels, again
     laying waste the notion that CO2 causes global warming. Thanks in advance Michael.

     Best regards,

     Jon

     I prefer actual empirical science to artificially constructed climate "models".  For
     example, the latest AQUA satellite data, as interpreted by Dr. Roy Spencer, showing the
     non-existence of the CO2 warming "fingerprint", laying waste to all of the climate
     models which predict otherwise.  Roy's most simple conclusion, after examining the
     actual real-time data was, " This means the models are all wrong...".
     There is to date, nothing in today's climate nor in the recent past which falls outside
     of the variability of normal climate change.  In fact, since 1998, average global
     temperatures have been falling in spite of rising CO2 levels, again laying waste the the
     notion that CO2 causes global warming.  In fact, changing CO2 levels are a result, not a
     cause of global temperature excursions, as anyone who understands CO2 solubility in
     water already knows.  Warmer (ocean) waters release CO2 and cooler waters absorb it, and
     CO2 lags, not leads, temperature in all known proxy data sets.  Al Gore managed to get
     it exactly backward in his documentary, and the scientifically illiterate climate
     alarmist sheep have dutifully followed in lockstep with that notion.
     []
     What does amaze me is the number of non-scientist climate pundits who chose to ignore
     the actual science in favor of terminally-flawed computer models which to date have
     failed to predict anything remotely accurate in terms of climate "change".  They seem to
     actually believe that a consensus of wrong answers will magically change the laws of
     physics and result in the desired outcome as predicted by the failed climate models.
     "If we wish hard enough for the sky to fall, then it must...".
     For the mathematically and scientifically literate, I highly recommend [8]this very
     straightforward look at the actual physics behind the "greenhouse effect" -- for all
     others, I suggest a new line of work as the field of scientifically illiterate climate
     pundits is already overcrowded.

     Kuhnian sense, how we got to where we are.

     And it's interesting to see Marty Weitzman's new work:
     [10]http://www.economics.harvard.edu/faculty/weitzman/files/modeling.pdf  Here's
     Krugman's recent summary:

     Martin Weitzman, a Harvard economist who has been driving much of the recent high-level
     debate, offers some sobering numbers. Surveying a wide range of climate models, he
     argues that, over all, they suggest about a 5 percent chance that world temperatures
     will eventually rise by more than 10 degrees Celsius (that is, world temperatures will
     rise by 18 degrees Fahrenheit). As Mr. Weitzman points out, that's enough to
     "effectively destroy planet Earth as we know it."

     Jon.

     Subject: AGW arguments

     Just for clarity, which of the following rationales for AGW do you find compelling:

      Here are some possible choices :

     1. All (or most) scientists agree
     2. The 20th century is the warmest in 1000 years [the "hockeystick" argument]
     3. Glaciers are melting, sea ice is shrinking, polar bears are in danger, etc
     4. The weather has been unusual: Hurricane Katrina etc
     5. Greenhouse models all agree that the climate should warm
     6. Sea levels are rising
     7. Correlation -- both CO2 and temperature are always increasing
     8. Models using both natural and human forcing accurately reproduce the detailed
     behavior of 20th century
     global temperature.
     9. Natural forcings are known well enough so remaining warming must be human-caused
     10. Modeled and observed PATTERNS of temperature trends ("fingerprints") of the past 30
     years agree
